有什么问题，我认为是在字符串编码中？!
更新:
代码在这里
//Download text -------------------------------------------------------------
private String DownloadText(String urlString){
InputStream in = null;
StringBuilder sb = new StringBuilder();
try{
in = OpenHttpConnection(urlString);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String line="";
while((line = br.readLine())!= null){
sb.append(line);
}
}catch(IOException ex){
}
return sb.toString();
}
//Parse JSON text -----------------------------------------------------------
private FBUser pasreJSON(String url){
FBUser user = null;
JSONArray json;
Log.d("JSON----------------",DownloadText(url));
try {
user = new FBUser();
json = new JSONArray(DownloadText(url));
for(int i=0;i<json.length();i++){
JSONObject object = json.getJSONObject(i);
user.id = object.getString("id");
user.name = object.getString("name");
user.first_name = object.getString("first_name");
user.last_name = object.getString("last_name");
user.link = object.getString("link");
user.username = object.getString("username");
user.gender = object.getString("gender");
user.locale = object.getString("locale");
}
} catch (JSONException e) {
e.printStackTrace();
}
return user;
}
最佳答案
在这一行:
json = new JSONArray(DownloadText(url));
将其更改为:
json = new JSONObject(DownloadText(url));
并且显然将 json 更改为 JSONOBject
关于android - 将字符串转换为 JSON 数组时出错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10306160/
